WebLet us calculate the determinant of that matrix: 3×6 − 8×4 = 18 − 32 = −14 Easy, hey? Here is another example: Example: B = 1 2 3 4 The symbol for determinant is two vertical lines either side like this: B = 1×4 − 2×3 = 4 … WebJan 4, 2016 · For the first minor obtaining: ( 3 0 − 4 − 8 0 3 5 0 − 6) M1 being row one column one we attain − 12 = 1. This is to be multiplied by the determinate of the minor. Now finding the determinant I did: Then: 4 times (− 8 0 5 0) giving 4(0 − 0) = 0 adding the determinants we get 0 + 0 + 0 = 0 So det M1 = 0(1) = 0.
